BIB AND BIX INPUT WALL PLATES
The BIX is an input module for sources in distant rooms or
locations. To the zone it’s in, it would be ‘Local’. For this
reason we identify it as such, think of it as stage left for
custom installation. It’s a feature unique to Q450. It
provides a differential balanced input to allow
transmission of an analog signal over long distances
without generating noise or signal loss due to conductor
impedance. BIX is an acronym for

tender. Enough with the fancy talk. It makes your iPod
sound good even though it’s far from the Q450 amp. It’s a
clever solution to a perennial problem faced in distributed
audio systems. We just decided that it’s too important to
not have integrated into the system.
You can connect any audio source as long as your
connecting cable has a 3.5mm (1/8th”) termination or an
adaptor on the other end. This includes, but isn’t limited
to, CD players, media servers, tuners, feature phones,
smartphones, iPods, laptops, desktop computers, tablets,
mp3 players, Bluetooth receivers, etc.
BIB INPUT PLATE WITH BLUETOOTH
The BIB is almost identical to the BIX above with added
Bluetooth capability. Bluetooth is normally on and
connected. When a jack is plugged into the AUDIO IN port
Bluetooth is disabled and the signal from the 3.5mm jack is
sent on the balanced line to the Q450 amplifier. BIB is an
acronym for
